9. Honda EB10000 Industrial Heavy Duty Portable Generator

When it comes to portable generators, hardly any manufacturer can rival Honda in terms of the quality of their products.

Honda generators consistently attract stellar reviews from the buyers worldwide. They are among the most preferred choices among professionals in the US.

Honda EB10000 is one of the most durable generators in Honda’s offer.

It is a serious 10000 watt industrial generator primarily designed for professional use.

The unit features an original Honda GX engine protected by a heavy-duty steel frame.

The control panel comes with a variety of outlets suitable for all sorts of electrical equipment.

The fuel tank capacity is 8.1 gallons.

As we would expect from a Honda generator, it is remarkably fuel-efficient.

The total runtime at maximum load is around 4.5 hours.

Running this unit at half load should get you around 7 hours of continuous operation.

One problem with generators of this size is that they are usually very loud.

Since Honda is known for manufacturing some of the quietest generators in the market like the super-popular EU2200i, we were curious to see if they managed to minimize the noise level in their largest generators too.

The EB10000 produces around 73 dB at maximum load.

This industrial generator is remarkably silent for its size and is quieter than most of its competitors in this wattage range.

One disadvantage of this generator is its hefty price tag.

That’s the price you need to pay if you want to buy a generator for a demanding job site.

This generator can potentially serve you for years or even decades.

If you really don’t want to go on any compromises and simply want to get the best generator to get you through long power outages or need a robust unit for a job site – get the Honda EB10000.

The generator comes with all standard electric outlets and receptacles. These include:

2 x 5-20R 120V AC 20A household outlets

1 x L5-30R 120V 30A outlet

14-50R 120/240V 50A outlet

The control panel has also got a 1L14-30R 120V 30A transfer switch ready outlet making this generator a viable choice for home backup power supply.

The generator has also got a low oil shutdown mechanism.

It also features an overload protection alarm that helps prevent damage to the engine.

Another good thing about this generator is that it’s both CARB and EPA certified.

The generator is 100% legal to use in all US states and is a viable choice for California residents.

10000 watt generators are usually noisy beasts. You certainly can’t expect them to run noiselessly, regardless of the load.

However, when preparing our list of 10 best 10000 watt generators, we examined the noise levels too. We were trying to find a generator that not only performs well but also minimizes the disruption caused by its loud engine.

We have found the Rainier R12000DF to be on the quieter side.

While not as quiet as the unrivaled Honda generators, the RD12000DF makes approx. 72 dB of noise at 25% load.

That is undoubtedly a better score than in case some of the older and bulkier contractor generators.

Overall, it is a quality 10000 watt generator and a good choice both for home and industrial use.
